Biodentine用于年轻恒牙牙髓切断术的疗效研究

Study on the efficacy of biodentine in the pulpotomy of young permanent teeth

目的:评价牙髓切断术中Biodentine应用于年轻恒牙牙髓意外暴露治疗的临床效果,针对临床治疗年轻恒牙意外露髓而提供新的思路和想法。方法:本实验选取了年轻恒牙意外露髓的患者70例,并随机分组为治疗组和对照组各35例,两组均行牙髓切断术治疗,其中在对照组中用Vitapex糊剂覆盖断髓,在治疗组中Biodentine覆盖断髓。比较两组患者临床疗效。结果:两组病例6个月后复诊,治疗组临床疗效与对照组相近,差异无统计学意义。两组病例12～18月后复诊,治疗组成功率高于对照组,两组比较有显著性差异(P<0.05)。结论:Biodentine应用于牙髓切断术治疗效果可行,可作为年轻恒牙意外露髓的一个新的治疗材料来选择,值得临床推广。

Objective:To evaluate the clinical effect of Biodentine in accidental exposure of dental pulp of young permanent teeth during pulp resection,and to provide new ideas for clinical treatment of accidental exposure of dental pulp of young permanent teeth.Methods:70 cases of young permanent teeth with accidental exposure of pulp were selected and randomly divided into treatment group and control group with 35 cases in each.Both groups were treated with pulp resection.The broken pulp was covered with Vitapex paste in the control group,and the broken pulp was covered with Biodentine in the treatment group.The clinical efficacy of the two groups was compared.Results:the patients in the two groups were re-examined 6 months later,and the clinical efficacy of the treatment group was similar to that of the control group,with no statistically significant difference.The power of the two groups was higher than that of the control group,and there was a significant difference between the two groups(P<0.05).Conclusion:the application of Biodentine in the treatment of pulp resection is feasible and can be used as a new treatment material for accidental exposure of pulp in young permanent teeth,which is worthy of clinical promotion.
